Alimak SE-Ex Hoist
Explosion-Protected Passenger and Freight Elevator for Hazardous Environments
The Alimak SE-Ex is a specialist hoist system engineered for hazardous and potentially explosive environments, where safety, compliance, and operational reliability are critical. Certified for ATEX and NEC standards, the SE-Ex enables safe vertical access for both personnel and freight — even under the most demanding industrial conditions.
Designed with a modular car structure, a shaftless rack-and-pinion system, and heavy-duty materials including saltwater-proof aluminium and galvanised steel, this hoist is ideal for oil refineries, petrochemical plants, mining operations and more.
